About me

After graduation from Yale University and Columbia
Law School, and after a tour of duty with the United States Marine
Corp, Zachary H. Sacks,
the managing partner of Sacks & Zolonz, LLP, came to California in 1963. Since that time, he has been active in all phases
of workers' compensation law. He has successfully represented clients from
trial level all the way to the California Supreme Court. He has been
instrumental in legislative activities concerning workers' compensation law and
has testified in the State Capital before legislative sub-committees on
workers' compensation issues on behalf of both clients of the firm, as well as
organizations which he has headed in his long career in California.


He holds the distinction of being the only two-time elected
President in the 30 plus year history of the Southern California Workers'
Compensation Defense Attorneys Association and he was the first and founding
President of the Statewide Attorneys Association called the California Workers'
Compensation Defense Attorneys Association in 1982 to 1983.  He
is the 4th recipient in the 26 year history of the California Workers'
Compensation Defense Attorneys Association of the prestigious Warren L. Hanna
Lifetime Achievement Award, conferred by his peers in May 2004.


He is a prolific author and sought after lecturer, having
first lectured to newly admitted lawyers to the California Bar on workers'
compensation law in 1973. Since that time, he has been an annual featured
speaker for multiple organizations and at multiple industry conventions
throughout both the State of California, as well as across the country. He has been a featured
speaker at the California Applicant Attorneys Association, the California
Workers' Compensation Defense Attorneys Association, the California

teacher and seminar instructor on various topics in workers' compensation law
for the firm's highly acclaimed workers' compensation training seminars for
attorneys and clients as well as functioning as a guest  teacher of
Workers Compensation law at UCLA Law School.


He has been the winning advocate for the firm's clients on
several precedent-setting cases in both the California Supreme Court and the
California Court of Appeal, which cases, to this date, are still cited by the
Courts in California. He and his firm represent employers, insurance carriers,
self insured administrators, school districts, and municipalities and uninsured
employers throughout Southern

  • George Ellis Corson IV

    I endorse this lawyer. We each represented different Uninsured Employers on a matter, and were each able to obtain favorable results for our clients. He was thorough, professional, and did a great job for his client. I would highly recommend him in the LA area. If I am unavailable, Zachary would be a great 2nd choice for your WC Defense in Southern California. ; )
